Abstract
A disposable sampling device for an apparatus for counting particles contained in a liquid, including a solid block-shaped housing connectable in a defined position to the apparatus. The housing has a member for introducing a sample therein, a device for metering a defined volume of the sample, and a chamber for containing a defined volume (V) of a diluting liquid. A diluting chamber is provided together with a device for simultaneously directing the defined volume of a sample and the defined volume of diluting liquid to the diluting chamber for obtaining therein a diluted sample. A device is provided for directing at least a portion of the diluted sample past a particle detecting member, and a signal transmitting member connects the particle detecting member and terminal member located at an outer boundary of the housing in a position corresponding to a location of a terminal member of the apparatus when the housing is connected thereto in the defined position.
